ABSTRACT: Towards the end of the 1980s, when the spawning grounds in the northwestern shelf (NWS) of the Black Sea were lingering with the effects of eutrophication and of an exotic invasive ctenophore, a series of basinwide international ichthyoplankton surveys pointed out an increase in the anchovies spawning in the southern half of the Black Sea. Later, with the help of international conser…
ABSTRACT: Specific regions of otherwise oligotrophic oceans seem to attract fish spawning and sustain significant abundances of fish larvae. The Sargasso Sea in the North Atlantic subtropical gyre is known as the spawning area of the Atlantic eels, but numerous other fish species also spawn in the area. In order to evaluate spatial variability of larval fish in the region, we examined species…
The South African chokka squid,Loligo reynaudi,spawns both inshore (≤70 m) and on the mid-shelf (71–130 m) of the Eastern Agulhas Bank. The fate ofthese deep-spawned hatchlings and their potentialcontribution to recruitment is as yet unknown.Lagrangian ROMS-IBM (Regional Ocean ModellingSystem-Individual-Based Model) simulations confirm westward transport of inshore and deep-spawn…
